If you know which jobs are bullshit then you don’t need to lower wages, you just eliminate the roles or at least stop hiring new people for them. None of this argument makes sense. I think you wanted to punish workers that did something you didn’t like and then got called out on it.

Also changing wages to encourage people into certain jobs is a capitalist economic technique. My idea of paying people for harder work (physical or intellectual work) is much closer to the socialist statement of “to each according to their labour”. Studying is a form of labour performed for free or even at cost to the person doing the labour. Higher wages for the educated are partially there to reflect this.
